title: Identification of incidental hepatic malignancy as photopenic defect on 99mTc-sestamibi myocardial perfusion imaging.
abstract: A 63-year-old male patient undergoing cardiac SPECT examination was incidentally found to have a large, photopenic (tracer-deficient) region in the right lobe of the liver. Follow-up abdominal CT scan demonstrated a corresponding large (7.8 cm × 6.9 cm), hypodense hepatic lesion. Subsequent CT-guided biopsy revealed metastatic carcinoma of uncertain primary source.
